High-Repetition-Rate Eye-Safe Intracavity Optical Parametric Oscillator
摘要
开展了连续激光二极管抽运声光调Q高重复频率人眼安全内腔式KTP光参量振荡器(KTP-OPO)的实验研究，研究了在相同二极管抽运功率下，基频光和信号光输出功率和脉冲宽度随调制频率的变化关系，获得了平均功率为1.6 W，脉冲宽度为6~10 ns，M2因子为5，重复频率为5~20 kHz的人眼安全激光输出，光光转换效率为5.3%。
Abstract
A high-repetition-rate eye-safe intracavity KTP optical parametric oscillator (KTP-OPO),pumped by an acousto-optically Q-switched Nd:YAG laser,is studied experimentally.The average output power and pulse width of the pump wavelength and the signal wavelength with respect to the repetition rate are analyzed at the same diode pump power. The average output power of 1.6 W and the pulse widh of 6~10 ns at the eye-safe wavelength are obtained with the repetition rate of 5~20 kHz,giving the optical-optical conversion efficiency of about 5.3% from diode power at 808 nm to OPO signal output, and the optical beam quality M2 factor is 5.
